The current conversion or update price to change an SRa to an SRb is $250 in the US. That price will be good until 31 July 2013. It will increase 50% to $375 after 31 July 2013. At the end of the year, we will drop the conversion "deal". Current cost for a block change is $752.38 and the SRb conversion uses exactly the same parts and requires the same alignment. So, at the end of the year the conversion may get pricey. Note that at $375, it is still half price.
If you can't get a unit in before 31 July, simply make an appointment before then for a conversion before 30 Sept 2013. This gives you 50+ days to decide to rob the piggy bank and 111 days to find a break in your schedule. If you have a firm appointment, the crew is good about turning the units around for a specific return date.
In the past few months, we have have done a thousand conversions in bulk. That is slowing down and in a few months it will start becoming similar to a regular repair. Hence the pricing change.
